will enable lean objects to select a function
Obtaining the maximum lean target as
The donation object of the idle article is inquired to obtain the label u of the poverty-relieving object;
recording idle item data of the subjects determined to contribute to poverty alleviation as
Will determine the idle item data for donation lean subjects
Feeding back the data to the poverty-alleviation object information data storage and conversion module to update the information data of the poverty-alleviation object u in real time;
idle item data that will determine donation poverty-depleted subjects
And (3) sending the poverty-relief information to a poverty-relief information encryption module for encryption treatment of poverty-relief information:
data set to be encrypted
Inputting the data into a data encryption formula for encryption.
7. The method according to claim 6, wherein the step S2 further comprises the steps of:
the poverty state index of the poverty alleviation object R obtained in the step S1
Sending the fund to a fund distribution module of a fund donation object for carrying out fund distribution, wherein the fund is realized by realizing idle articles in a change processing module, and the real-time change fund amount is expressed as
And will be
Inputting the obtained data into a fund distribution module of a fund donation object to distribute funds;
setting a set of fund distribution modes
Wherein p denotes an allocation pattern, q denotes a pattern class, and
for any of the fund distribution modes
Carrying out representation;
the expression of the design pattern evaluation function is as follows:
wherein
Indicates the maximum index of the poor state,
the method comprises the steps of representing the average value of poverty state indexes of all objects to be poverty depleted at the current moment, G representing the number of people of all objects to be poverty depleted at the current moment, and r representing the label of any one person of all objects to be poverty depleted at the current moment;
by comparison
To find the current time so that
Having a maximum value
And (4) performing fund distribution of the poverty-supporting object as a fund distribution mode at the current moment, transmitting the fund distribution information to the poverty-supporting information encryption module for encryption processing of the poverty-supporting information, wherein the method is the same as the encryption method in the step S2, simultaneously feeding back the fund contribution information to the poverty-supporting object information data storage and conversion module for information updating, feeding back the fund contribution information to the change processing module, and updating the amount of the donatable fund in real time.
